Description: With respect to the currently active image, determines how the mouse wheel functions and changes options that govern how new images behave.


  • Sequence images use new windows: When checked, new images (taken as part of a sequence) will use new display windows rather than reusing the current image display window.  Note that this option does not apply to temporary frames (auto focus, frame and focus, plate solve) which always use the same window for display.  If this option is not selected, sequence images will replace one another in the same window frame.
  • Use mouse wheel to:
    • Stretch Image:  Selecting this option, the mouse wheel will stretch the currently selected image's white point (holding the ALT key while moving the mouse wheel will move the black point).
    • Zoom Image:  Selecting this option, the mouse wheel will zoom the currently selected image.
